Number formatting function ??

[Bikash Paul]

Hi,
I want to write a java function which will format a number upto four digit after decimal and if the number in fifth position after decimal is greater than and equal 5 then it should add 1 with fourth position number and if that number is smaller than 5 than it should trim the rest number after four digit after decimal.Can any one please give me some idea how i can do that.
Thanks & Regards

Multiply your number by 10000, use java.lang.Math.round(double a) and divide the result by 10000.

Try this:

public static String formatNumbers(double src) {
   Format df = NumberFormat.getInstance();
   if (df instanceof DecimalFormat) {
      ((DecimalFormat) df).applyPattern("###0.0000");
   }
   return ((NumberFormat) df).format(src);
}
